What should I tell my friend?

I'm going to be very honest with who ever reads this but you cant tell a soul and please don't report this please! Ok, my best friend just recently told her other bf that she harmed herself a long time ago. Don't worry she doesn't anymore she knows it was wrong. And it wasn't in a harmful place so it wasn't a big deal except the fact she thought about it. Ok, her friend said she wouldn't treat her differently. My bf comes to me to talk we tell each other everything so I knew and she tells me what going on and stuff. She tells me that she feels really awkward around her bf and she can tell her bf feels awkward around herself. Her bf doesn't seem as happy and fun as she used to and that bf is in next grade and they watched a video about a girl who did the same but keep doing it and now its getting worst. I don't know what to tell her please help and please don't tell anyone! She say that most people who do it want to die she doesn't she was sad one so chill out you don't need to know why, ok she had a reason and won't do it again ok!!!! thx and again don't tell!!!!

You should tell her that your there for her. No matter the matter. A best friend will always listen and a best friend will never judge.

The thing with her bf is just going to have to play itself out. He has to decide if he's comfortable dating her, and he may need some time to think it through. Just be there for her like supermatts says.
